10 Maintenance

This section covers basic operational maintenance procedures for Solo. For repairs not covered in this manual,
contact 3DR Support or an authorized Solo Service Center.
Solo's exterior components are designed to absorb impact from hard landings and protect the core electronics.
If damage is sustained to Solo's legs or motors, replace them with official 3DR parts from store.3dr.com or an
authorized retailer. 3DR offers an extended controller battery upgrade with double the capacity so you can fly longer
between charges. Before opening the battery bay or performing any maintenance on Solo, always ensure that Solo
is powered off with the battery removed.

10.1 Controller Battery Replacement

To replace the controller battery, open the battery door on the back of the controller. Remove the foam block and
disconnect the battery from the port in the side of the battery compartment. To install a battery, connect the battery
to the controller, and, for standard-size controller batteries, use the foam block to pad the empty space in the
compartment. For information on safely storing spare controller batteries, see Section 4.10.

10.2 Calibrations

Use the Solo app to perform compass and level calibrations when prompted by the controller. Remove Solo's
propellers before performing calibrations.
10.2.1 Compass Calibration
To calibrate Solo's compass, connect the app to Solo Wi-Fi, go to Settings > Solo and select Compass Calibration.
Ensure that Solo and the controller are powered on with the propellers removed. Solo requires an interference-free
environment for compass calibration, so ensure that you are away from metal buildings, reinforced concrete, or
other metal structures before starting calibration.
